UPDATE: Beltre could be out for season with testicle injury

The Mariners placed third baseman Adrian Beltre on the 15-day disabled list with a severely contused right testicle.

Beltre suffered the injury in the ninth inning when a ground ball off the bat of Chicago White Sox shortstop Alexei Ramirez hit Beltre in the groin. Beltre does not wear a protective cup. He finished the 14-inning game.

Manager Don Wakamatsu said Beltre might need surgery because of bleeding in the testicle. If surgery is required, it could take months for Beltre to recover.

Infielder Josh Wilson was promoted from Triple-A Tacoma to replace Beltre on the 25-man roster. Wilson will start at shortstop tonight against the Yankees.

Beltre has played nine games since returning from left shoulder surgery Aug. 4 and was riding an eight-game hitting streak. For the season he is hitting .275 with five homers and 31 RBIs.

The injury deals a major blow to the Mariners, who are hanging around the fringe of the American League wild card race as they enter a four-game series against the New York Yankees.

Wilson was hitting .245 with one homer in 16 games with the Rainiers since July 14. He was with the big league team for nearly a month after being claimed off waiver from the San Diego Padres on June 19. In four games with the Mariners he went 0-for-2 and scored two runs.
